To all whom it may concern:

Be it knownth'at L'B-UDDE SOHIFFENHAUS'" acitizen of the United States, and a; resident of Newark, in the countyof. Essex and State of New Jersey have invented a new and" Improved Machine for Forming Paper Hat Rings, of which the follow-ing is aful1,- clear,

and exact description.

quickly and. always, of the samesize.

Another object of the. invention: is-to proa vide a machine: for making paper rings for supportingv hats Wherein the. ringsv are, formed with beads or rolled edges, which, act both as a stiffening structure; and as:

means for preventing injury tothe hat when the ring is in use. 7

A still further object in View is to provide a machine for forming paper rings-for. supporting hats wherein themach ine wraps g I ofidentlcal construction so thatthedescrip a coveringstrip, ofpaper over either edge or both edges of the ring.

As: indicated in Figure? 1; there is prov ided'" shafts. 2- and 3, shaft 2 having .igrear wheels; 4: rigidly secured thereto whilei -theshaift is provided with gear wheels 5' meshing withgear wheels/L. In addition, thejsha-ft 3 ijs' provided with a. driving pulley-'3 jwhich may be; driven from any suitable source of power, The sha-ft 3is provided with a pail-r of feed rollers 6,. said rollers being: identical so that the description of one. will. apply t'oboth.

ers 6' and 7 are spaced apart for'engaging the strip of paper- 8? near the respective-- edges. Inv fact, -strips .of' tissue paperor As indicatedfn:Figure2, the various rollsaid strips; engagingithe" respective rollers" 6 andsuitable other feeding and: forming rollers hereinafter. fully, described? whereby when the finishedring is provided rolled edgesrwillibe presented; and said edges :Wi'll'."

becovered, by the stripsg9and 1'0; Thetwof top rollers 6 co act with the respective pairs of feeding and formingrollers 11, 12 and 13 .so as to turnover the edgesof the strip 8 and form the? bead 14.

Asindicated in Figure 3, the. rollers 6 are provided with grooves '15 which: co-act: with; .thegrooves: 16 on the rollers 11.. A belt 17 roundincross section is. provided for each of the rollers 11, saidbelts being. preferably spiral. Wire belts as shown particularly in Figure 8. Thesev belts force part ofthe strip; 8 and the strips 9 and; 10 into the grooves'15. As the. strip 8.and-ithe:.stripsi9 and 10 leave the rollers 11,. the e'dge'srof all these strips engage the, respective folding I cams18 and 119, (Figure-4,) said cams caus ing the strip 8 Witlrthestrips 9 aIldlQEtUbeT turned up and then folded over so that the 1 the respective rollers 6 and 7 rollers 12 will complete the bead or rolled edge 14. However, part of the respective belts 17 are in the bead or folded edge 14 and must be removed. In order to accomplish this removal, pulleys 20 and 21 are provided, said pulleysbeing supported by suitable bolts or pins 22 and 23 adjustably positioned in the respective slots 24 and 25. The pulleys 20 and 21 are offset toward a central line between the respective rollers 13 as indicated in Figure 2 whereby as the strip 8 and the belts 17 move forwardly, the belts will be gradually moved out of the bead or turned over edge 14 as indicated in Figure 8. This will leave the bead somewhat open and the rollers 7 will then act to close the bead.

It will be noted that the lower runs of the respective belts 17 are inclined toward a central line of the machine so that the lower runs of the belts will be pulled out of the folded edge 14. The strips 8, 9 and 10 passing. through the machine will be acted on as just described and will finally pass between In passing from between the rollers 6 and 7 as indicated in Figures 1 and 6, a knife or cutter 27, (Figure 6) cuts the respective slits 28 and 29 for forming the tongues 30 and 31, after which, the knife 32 cuts the strips 8, 9 and 10 so that a single blank 33 is discharged. As the machine continues to operate, one or more slitting knives 34 function to provide the various slits 35 in the end of the blank 33 opposite the tongues 30 and 31. In forming the slits 35 the paper is fed further through the machine and the operation of forming the tongues 30 and 31 is repeated. After a blank has been formed,

i ends of the block are locked together and a complete ring is presented ready for use. It will be noted that the complete ring as shown in Figure 10 is provided with beads or rounded edges 36 and 37 and that by po sitioning the tongues 30 and 31 in different sets of slits 35, the size of the ring may be varied. It will, of course, be evident that one bead or edge. could be provided for the finished ring instead of two. Also, it will be evident that the strips 9 and 10 could be eliminated and the beads or turned over edges provided. However, it is preferable to use the strips 9 and 10 because the paper 8 is heavy paper of some kind and often cracks when being turned over at the edges. This will present a rough surface which is undesirable and, therefore, the covering or wrapping of the tissue paper strips 9 and 10 around the edges functions to positively present a smooth edge which will not injure the hats when the rings are in use. Inuse,

the rings are to be placed over the crowns of hats, particularly mens hats when they are stored in boxes or even placed on shelves, whereby the crown will be supported above the support of the rim.

When the machine operates, the same may be caused to function at high speed or low speed and the various strips 8, 9 and 10 fed into the machine from various sides. As these strips pass over the various rollers heretofore described, the edges will be formed and finally separated blanks 33 will be successively discharged from the machine. In forming the two rollers 6, preferably each is formed with a cut-out or notch 38 which is substantially filled by a wedge-shaped plate 39 carrying block 40 of hard wood or soft metal, said block being adapted to act as an anvil against which the cutter 32 presses without cutting a finished blank from the strip 8. Therollers 7 are likewise formed with a notch 41 which is substantially filled by a wedge-shaped member 42 carrying the various knives or dies 27, 32 and 34. These members may be held in place by screws or any suitable means. The wedge members 39 and 42 also may be held in place by set screws or other suitable means. The shafts 2 and 3 are mounted in suitable bearings, the bearing of shaft 2 being preferably fixed in any desired manner while the bearing of shaft '3 is slidingly mounted in suitable slots in the frame whereby different size rollers 6 and 7 may be used. Also the various rollers 6 and 7 are slidingly mounted on the respective shafts 2 and 3 and held in any desired adjusted position by suitable set screws. The various rollers 11, 12 and 13 are also slidingly mounted on their supporting shafts and locked'in different positions by suitable set screws. The slots 24 and 25 permit a proper adjustment of thepulleys 20 and 21 whereby the belt 17 may properly function. It will be noted that the lateral adjustment of the rollers 6 and 7 and also the rollers 11, 12 and 13 is to permit the formation of rings of different heights or widths, according to the various demandsoon the manufacturer. When a given pair of rollers 6 and 7 are used, as for instance, the size shown in Figure 1, the length of the blank will always remain the same but the width may be varied as desired. If a different length is desired, a different size set of rollers 6 and 7 should be used.

What I claim is 1. In a machine for forming paper rings for hat supports, a pair of rollers, a plurality of cutting-members on one of said rollers for cutting a strip of paper passed aroundthe other roller, said cutting means acting to cut the paper into sections and to out each section so as to provide a slit at one end, and a tongue at the opposite end,

rality of roller structures co-acting with the" first mentioned roller structure acting on the turned over edges for completing the bead,

and means for severing said strip of paper into lengths.

3. A machine of the character described, comprising a pair of feed rollers, each of said feed rollers having a groove in the periphery, said feed rollers being adapted to receive a strip of paper which will extend from one roller to the other and overlap said grooves for an appreciable distance, a plurality of forming rollers for each of the feed rollers, each of said forming rollers being provided with a groove arranged in line with the grooves in the feed rollers, a belt round in cross section passing over said forming rollers whereby the belt passing over the first set of forming rollers will push the paper into the grooves in the feed rollers and will hold the paper in said grooves until the paper moves away from the belt, means all) for turning the edge of said paper in a preliminary manner until the same is partially folded over said belt, certain of saidforming rollers acting on said turned o'verpaper for completing the turning action so as to present a hollow bead on each edge of said paper, and means co-acting with said feed rollers for cutting said paper into lengths.

4. A machine of the character described,

comprising a pair of feed rollers, each roller having a peripheral groove, a plurality of forming rollers co-acting with the feed rollers, each of said forming rollers having a groove in line With the grooves of the feed rollers, a pair of cams, said cams being arranged so that the one will operate in connection with each of the feed rollers for turning over a strip of paper passed over i the feed rollers, said camsacting to turn the edge of said paper, a pair of belts round in cross section passing over all'of said forming rollers, a pulley Wheel for each of said belts offset toward each other from a straight line with said forming rollers, and

means co-acting with said feed rollers for cutting the paper fed over the feed rollers into lengths.

5. In a machine of; the character described, means for receiving a strip of paper and turning the edge over for formlng a" hollow bead, said means including a pair of belts round in cross section, a cam acting on each edge of the paper strips for pressing the folded edges over said belts, a pulley for each belt spaced from said rollers andalso' ofi'set towards each other from a straight line from said pulleys whereby as the paper passes from certain of said forming rollers the belts will move out of said bead, and

means for cutting said paper into lengths.

6. In a machine of the character described, means for receiving a strip of paper 7 and forming beads on each edge, means for 7 cutting the paper into lengths after said beads have been formed, and means for forming slits at one end of said severed lengths and tongues at the opposite end whereby the tongues may be inserted into said slits for holding the lengths into circular formation.
